THE STUDY OF SALT-RESISTANT POLYMERIC REAGENTS

This article discusses several options for the use of polymeric reagents PS (PS-1) and 34 Termopas-resistant polymineral aggression. One of the options – is the use of fresh and mineralized polymer solutions based on the SS agent. As well as the creation of fresh and mineralized polymerclay solutions with the addition of chemical products and Termopas PS-34. Introducing the reagents tested technology in wash liquid as in a dry form or as a preformed aqueous or saline. The effect of different salts on the properties of drilling fluids with the addition of the polymer. Special attention is given to those compositions, when there is destruction of a solution or a significant thickening system. Found formulation with the necessary structural and rheological parameters and filtering parameters. It is noted that in this case it is necessary to strictly observe the recommended solution preparation technology.

The polymeric reagent as a whole substation meets the parameters of declining filtration and impart sufficient structural and rheological parameters in salt solutions. At the same time, the natural and artificial clay solutions at minimum concentrations of PS supplements in liquid form does not occur, and improve the rheological and mechanical properties of the structurally above acceptable values. However, to avoid the introduction of PS-1 of any reagent in solution in dry form.

Reagent-34 Termopas not all types of forming salts with the required filtration system and rheological properties. Also additives Termopas-34 does not have a stabilizing effect on the cement. However, in the fresh and saline mud, with appropriate Termopas-34 reagent concentrations are achieved satisfactory filtration and structural and rheological properties of the washing liquid.
